replication see <a class="xref" href="logical-replication.html" title="Chapter 31. Logical Replication">Chapter 31</a>.

Unlike most system catalogs, <code class="structname">pg_subscription</code> is
shared across all databases of a cluster: there is only one copy

normal users, because it could contain plain-text passwords.
